BackgroundThe aim of this study was to determine and compare changes in arterial oxygen saturation (SpO2 ) and heart rate (HR) in healthy term infants with and without maternal bonding.MethodThis was a prospective observational study in healthy term infants. SpO2 and HR were recorded from 1 to 10 min after birth. After this, SpO2 and HR were registered at 15, 30 and 60 min and then at 12 and 24 h after birth. SpO2 and HR were measured with a pulse oximeter.ResultsA total of 216 healthy term infants were divided into three different groups: 136 (63%) born by vaginal delivery, 56 (26%) born by cesarean section with bonding, and 24 (11%) born by cesarean section without bonding. No difference in SpO2 was found in babies born by cesarean section with or without maternal bonding. In neonates delivered vaginally, SpO2 was significantly higher during the first 10 min after birth than in neonates born by cesarean section with bonding (P < 0.05). Compared with infants born by cesarean section without bonding, this tendency was not significant. In general, HR was similar across groups, although, for infants born by cesarean section, neonates who received bonding had lower HR from 6 to 8 min (P < 0.05).ConclusionsIn healthy term newborns, maternal bonding in infants born by cesarean section did not have effects on SpO2 . Some differences were observed in HR between infants born by cesarean section with and without bonding.© 2016 Japan Pediatric Society.
